Earlier this year I traded in my Wii and old Xbox for a used Xbox 360 at GameStop. My youngest is a special needs boy and the Kinect sensor is a great way for him to play games and exercise without the fine motor skills that a game controller requires. The OEM power supply failed after 30 days. I returned everything under warranty and received a replacement OEM power supply. This then failed 30 days later. The staff took care of me and gave me the THIRD regular power supply. It took about 2 months before it failed. Enough! Why would you continue to put up with those failing OEM power adapters (every rep I spoke to knows about Xbox Slim OEM power adapter problems). I read the review on Revain and decided to buy this one from YCCTEAM. My youngest and I only play 2-3 hours 3 days a week. So far, so good. It's only been about a month so I'll update the review in a few months and let you know how it holds up over time. Four stars so far!
